[libcxx-dev] ninja check-libcxx failing when running under sudo

[JF Bastien via libcxx-dev]

Do you have a list of the tests that fail, and why? It would be interesting to understand whether those failures are accurate (and we should fix libc++), or whether the tests are erroneous.

It seems like a bad idea to run tests under sudo… but we probably should look into why you’re seeing that behavior.

For example, some of the tests check the permission of the file/directory after the filesystem operation, but sudo privilege overrides it. I wonder if it’s possible to guard a test based on the user’s privilege? Thanks!
